520 $a The purpose of this investigation was twofold: (a) to critically review the quality of the methodology employed in published studies of child and adolescent treatments for obsessive-compulsive disorder (OCD) and (b) to conduct a meta analysis of published and unpublished studies of pharmacological and behavioral treatments for pediatric OCD.
520 $a For the methodological review, an exhaustive literature search yielded 93 published studies of various study designs. The threats-to-validity framework was applied, with the results indicating that the treatment literature attended acceptably to some threats but insufficiently to several others. Specifically, power was adequate to detect a large treatment effect, and reliable instruments were used in half the studies. Internal validity was perhaps the most problematic; that is, only 14% of the studies used a study design employing a control group with random assignment. With regard to construct validity, most studies failed to use multimodal assessment and relied primarily on indirect forms of measurement. Demand characteristics were free to influence results in most studies, since placebo control was used in only 12% of the studies. Finally, external validity suffered from the failure to report basic subject or clinician demographics. Prescriptive suggestions for improving treatment research are offered.
520 $a Thirty-two studies, including controlled and uncontrolled trials, were included in the meta-analysis to determine the efficacy of both pharmacological and behavioral treatments. Pharmacological treatments included clomipramine, citalopram, fluoxetine, fluvoxamine, paroxetine, and sertraline. Behavioral treatments consisted of variants of cognitive-behavioral therapy (CBT) with exposure-and-response prevention (ERP). The literature was also gleaned for single-subject studies that met sufficient inclusion criteria. However, only 5 studies were found, and these were not analyzed by meta-analysis.
520 $a Hierarchical linear modeling (HLM) revealed a significant, standardized mean effect size of 1.32. The study design variable, whether a study used a control group, accounted for 77% of the reliable variance. Study design was used as a covariate. Thus, none of the other moderator variables, including type of intervention (pharmacological versus behavioral), accounted for any significant variance. Well-designed, head-to-head comparative studies are needed to compare the relative efficacy of treatments. Implications for future research and the limitations of the current study are delineated.
